Concrete tunnel elements
Built for tunnels.
Chosen for the most complex projects.
When Denmark invests heavily in the complex infrastructure projects of the future — from the M5 Metro and the Third Limfjord Crossing to the Marselis Tunnel and advanced wastewater solutions — extraordinary demands are placed on tunnel elements, materials and reliability of supply. At CRH, we develop and deliver prefabricated concrete tunnel elements designed to handle even the most demanding underground conditions.
CRH is one of the world’s largest players in building materials, which enables us to draw on extensive international experience and technical expertise from complex infrastructure and tunnel projects across Europe. At the same time, we are locally rooted in Denmark with strong competencies in complex construction projects and high standards for quality, reliability of supply and long service life.
As the Danish part of CRH, we combine global know-how from tunnel projects in England, France and Romania with a strong understanding of Danish conditions, standards and ways of working. This enables us to translate international experience into robust and well-documented solutions for Danish infrastructure projects.
Our concrete tunnel elements are developed with a focus on strength, durability and precision. They form a central part of modern tunnel construction, where requirements for watertightness, service life and efficient assembly are crucial to both project economics and progress.
When risk must be minimised and deliveries must work from day one, clients and contractors choose CRH.
Facts:
CRH has extensive experience in tunnel construction and prefabricated concrete tunnel elements from a number of Europe’s largest infrastructure projects:
- Grand Paris Express, France
– One of Europe’s largest infrastructure projects
– Delivered approximately 60 km of new metro with extensive tunnel construction out of a total of 120 km - Nice Metro & tunnel projects, France
– Complex tunnel construction in densely populated urban areas - Bucharest Metro, Romania
– Expansion of underground infrastructure in urban environments - Tunnel projects, United Kingdom
– Large infrastructure schemes with demanding geotechnical conditions

Scale, logistics and specialised tunnel elements
CRH’s strength lies in our ability to deliver complex solutions at scale. Our portfolio encompasses prefabricated concrete elements, specialised tunnel elements, rainwater systems and solutions for critical infrastructure. This makes it possible to consolidate deliveries and reduce interfaces within the project — a clear advantage in large tunnel and infrastructure projects.
With a strong national production and logistics setup and significant storage capacity, we ensure continuous deliveries of concrete tunnel elements — even when the TBM (Tunnel Boring Machine) is operating around the clock and progress cannot afford to stop.
In TBM-driven projects, a stable supply is essential. Even brief delivery interruptions can have direct consequences for pace, economics and the overall risk profile of the project. Our setup is therefore designed to deliver on time, in the required quantities and with consistent quality — throughout the critical phases of tunnel construction.
This gives our clients a real competitive advantage: controlled progress, reduced risk and a high degree of certainty in the project’s most sensitive processes.
Quality is non-negotiable. All our solutions meet stringent requirements for documentation, safety and durability — key parameters in infrastructure that must perform for decades.

A focus on sustainability and collaboration in tunnel projects
In modern tunnel construction, sustainability and resource optimisation are central requirements. At CRH, we work purposefully to reduce the CO₂ footprint of our concrete elements and optimise material consumption — without compromising on strength or quality.
We collaborate closely with contractors and consultants from the earliest stages, where the choice of tunnel elements and construction solutions has a significant impact on buildability, economics and carbon footprint. Our approach is proactive, solution-oriented and based on solid experience from international tunnel projects.
We deliver strength in the materials, certainty in the supply chain and value in the collaboration — and we are ready to be chosen when tunnel projects and infrastructure are at their most complex.
